Thus the efficient image compression method should be used to decrease the bit rate. The image compression method based on wavelet is used more widely nowadays. However  two dimensional wavelet is only the tensor product of the one dimensional wavelet whose support region of basis function is extended from interval to square. Contourlet is an image multiscale geometric analysis tool  which could represent image sparsely and has strong capability of nonlinear approximation. The basis function of contourlet is multidirectional and anisotropic. Nevertheless  contourlet is redundant. So the non-redundant Wavelet Based Contourlet Transform (WBCT) is used in this paper. The SPIHT algorithm is very efficient way to coding the significant coefficients. And the improved no lists SPIHT is more easy to implemented by hardware. Image compression method based on the combination of both wavelet based contourlet transform and no lists SPIHT coding is proposed in the paper. Experiment shows that compared to wavelet based scheme the contourlet scheme can reserve the texture of the image. For barbara test image when coding at low bit rate the PSNR can improve about 0.2dB. 2010 IEEE.   Theoretical design and circuit implementation of multidirectional multi-torus chaotic attractors 期刊论文  OAI收割 IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-REGULAR PAPERS, 2007, 卷号: 54, 期号: 9, 页码: 2087-2098 作者:  Yu, Simin;  Lu, Jinhu;  Chen, Guanrong   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/07/30 fourth-order double-torus chaotic circuit  multidirectional  multi-torus (MDMT) attractor  saturated function series  step function series   Research on wave forces acting on the unit length of a veritical breakwater by tests and a numerical model 期刊论文  iSwitch采集 Journal of hydrodynamics, 2006, 卷号: 18, 期号: 5, 页码: 512-519 作者:  Hu Jin-peng;  Yu Yu-xiu;  Zhu Liang-sheng 收藏  |  浏览/下载：32/0  |  提交时间：2019/05/10 Vertical breakwater  Uni- and multidirectional irregular waves  Wave forces acting on the unit length  Short-crest wave model   Experimental verification of multidirectional multiscroll chaotic attractors 期刊论文  OAI收割 IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-REGULAR PAPERS, 2006, 卷号: 53, 期号: 1, 页码: 149-165 作者:  Lu, JH;  Yu, S;  Leung, H;  Chen, G   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/07/30 circuit implementation  hysteresis series  multidirectional chaotic attractor  multiscroll chaotic attractor  saturated series
